After reading a few more threads I am trying to make sure I have the correct studs for the job.

I keep reading where there were changes in drum design in 68 and since my car is a Oct 68 car with a mixture of early parts. I see where some A-body guys are having trouble finding studs that have the correct shoulder and do not mic out to the correct design of the their drums.

My problem is (as always) that if I remove everything, making the car inoperable, and then find that it needs a hard to find part weeks out of deliver I am screwed.

If anyone has recently pulled one of these and has a source or part number it would be greatly appreciated. This is for the front but I would like to buy a few extra rear studs while I am there so both specs would be awesome.
